Recipe Tips

Preparation

Sift cocoa into medium bowl. Bring cream and ground coffee to boil in heavy small saucepan, stirring to blend. Remove from heat; cover and steep 10 minutes. Strain cream through fine sieve into another bowl, pressing on coffee grounds to release as much cream as possible.

Bring sugar, corn syrup, 1/4 cup water, and coffee-flavored cream to boil in medium saucepan, whisking until sugar dissolves. Boil 1 minute, brushing down sides of pan with wet pastry brush. Remove from heat. Whisk in chocolate, butter, and vanilla. Pour 1/4 of chocolate mixture into cocoa to moisten, then add remaining chocolate mixture, whisking until sauce is smooth and shiny. DO AHEAD Can be made 1 week ahead. Cool. Cover and refrigerate. Rewarm sauce over low heat before using.
